Simulation Roll/Pitch/Yaw through MissionPlanner-SITL

Hi there

On the net I find some information but very complicated so I wanted to ask this question to the group relating to the possibility of simulation via MissionPlanner

I don’t speak of automatic navigation but of tuning for example to optimize Roll and DesRoll … or Pitch and DesPitch … in short, all those parameters that are refined after Autorune

The most immediate question is: by loading the .params file in Missionplanner, through SITL, is the navigation responding to the PID? Let me explain better … if I modify the pids of roll/pitch/yaw and then I introduce weather variables (wind, etc.), is the simulation real and consistent with the changes?
I mean by Sitl without loading other external programs that run in Linux, Ubuntu, Python etc.

Can you clarify me better on function and if it exists and is reliable in the real world?

Thank you
